Space requirements The washer/dryer dimensions are shown in the figure below: Location of Canadian terminal block (gas models) 27 3 /16" 69 cm 5 1 /2" 5" 14 cm 12.7 cm Location of Canadian terminal block (electric models) 5/8" 1.6 cm 27 1 /2" 69.9 cm Dryer 3 1 /4" 8.3 cm Connection Gas Manifold 41" cm Location of dryer terminal block on electric models and power supply cord on gas models (except Canadian) 3/4" 1.9 cm 38 3 /16" 97 cm 13 1/2" 34.3 cm 71 1 /2" cm 1 1 /8" 2.9 cm 39 5 /32" 99.5 cm 3/8" min..95 cm Washer Exit location of washer drain hose 13 1 /2" 34.3 cm Location of washer water valve connections 27 1 /2" 69.9 cm 3. Location Each appliance should be located to permit adequate room in front for loading the clothes, and sufficient room behind for the dryer exhaust system and washer hose connections. The dryer is factory-ready for rear exhaust. To exhaust out the left side, use an accessory exhaust kit available from your dealer. Instructions are included with the kit. When installing the dryer, the following minimum clearances to combustibles apply; clearance to wall and sides 0 inches. Top 0 inches with outside exhaust; rear 0 inches with outside exhaust. It is important to make sure the room has an adequate air supply for gas combustion and/or drying operation. This is particularly important for multiple unit installations. The operation of the dryer may affect the operation of other gas appliances which take their air supply for safe combustion from the same room. If in doubt, consult the appliance manufacturers. An adequate means of ventilation must be provided that opens directly to outside air. For gas washer/dryer installations where dry cleaning machines are also installed, the sources of makeup air and air movement to the dryers must be located away from the dry cleaners. The appliance must not be installed or stored in an area where it will be exposed to outside weather, or where water may freeze, since the washer will always retain some water in the water valve, pump and hose areas. The area must be kept clear and free of combustible materials, flammable vapours or liquids. Operating temperature should be above 15 C (60 F). Page 2

4 IMPORTANT: This appliance is not IPX4 (splashproof) rated. It must not be installed or stored in an area where it will be exposed to water. Do not use a water hose or wet cloth to clean the outside of the appliance. For best performance, the appliance must be installed on a solidly constructed floor. Wood floors may need to be reinforced to minimize vibration and/or unbalanced washer load situations. Carpeting and soft tile surfaces are contributing factors in vibration and/or tendency for an appliance to move slightly during the washer spin cycle. Never install the appliance on a platform or weak supported structure. 4. Unpacking IMPORTANT: Notice that the washer hoses are tied up with a shipping strap. The upper straps on the back of the machine should not be cut or removed until the machine is ready to be installed. To remove appliance from transit base. Cut both lower shipping straps where they wrap around the crate bottom, DO NOT BE ALARMED as the tub will jump up when the last strap is cut. Lay two of the carton corner posts on the floor, and tip the appliance on its back to lay across the carton corner posts. Pull loose straps from the bottom of the washer. Release the transit base by removing the two wire hooks with a screwdriver as shown. Locate the metal buckles attached to the shipping straps at back of washer. Carefully cut away straps near both buckles, completely removing both buckles from the washer. Pull loose straps from back of washer one at a time until all straps have been removed. Loosen the leveling feet lock nuts. Place appliance in its intended location and adjust feet until the top is level on all four edges, before tightening lock nuts. A carpenter s level should be used on all four edges of top cover. 5. reversal swing direction can be successfully changed using the following procedure: Upper Dryer Dryer : 1. Remove the two screws in the hinges that secure the hinges to the front panel. Slightly lift the door and remove from the dryer front shroud. Set the door aside. 2. Remove the two hinge hold covers and the door catch cover and transfer them to the other side of the door opening. 3. Move the following parts to the opposite side of the door: 2 hinges and 4 screws, 4 colored door screws, door strike and screw, inner door cover plate and screw. 4. Reposition the door with the relocated hinges into the slots opposite of the original mounting position. Seat the hinges fully into the slots and screw the hinges into the front panel.

5 Washer : 1. Swing door fully open and remove the two screws securing the hinges to the front panel. 2. Lift door slightly and pull door out of plastic front shroud. Press the plastic shroud toward the cabinet, should the hinge bind. Set the door aside. 3. Transfer the hinge hole covers to the opposite side of the door opening. 4. Transfer the hinges to the opposite side of the door, while transferring the colored screws to the previous hinge location. Position the hinge pin to the outside of the door panel. 5. Reposition the door into the plastic shroud and seat the hinges fully into the plastic shroud. Secure the hinges to the front panels with the hinge screws. 6. Close the door and run the washer through a wash cycle to check for leaks. If leaks occur, reposition the hinges to allow more contact between the lower edge of the door liner and the door boot. Hinge Hole Covers Hinges Screws Screws 6. Dryer exhaust The dryer must be exhausted to the outside air. This is necessary for gas combustion (on gas models), and will also prevent large amounts of moisture and some lint from being blown into the room. WARNING: Plastic or non-metal flexible duct presents a potential fire hazard. NEVER USE PLASTIC OR NON-METAL FLEXIBLE DUCT. If your existing ductwork is plastic, non-metal or combustible, replace it with metal. Plastic flexible duct can kink, sag, be punctured, reduce airflow, extend drying times and affect dryer operation. USE A MINIMUM OF 100mm (4 ) DIAMETER RIGID ALUMINUM OR RIGID GALVANIZED STEEL DUCT. Do not use smaller duct. Ducts larger than 100mm can result in increased lint build-up. Any lint build-up should be cleaned regularly. If flexible metal must be used in some areas, use the type with a stiff sheet metal wall. Do not use flexible duct with a thin foil wall. Serious blockage can result if flexible metal duct is bent too sharply. Never install any type of flexible duct in walls, ceiling or other concealed spaces. Keep exhaust duct as straight and short as possible. Exhaust systems longer than recommended can extend drying times, affect dryer operation and may collect lint. Secure joints with proper duct tape. Do not use screws. DO NOT EXHAUST DRYER INTO ANY WALL, CEILING, CRAWL SPACE OR OTHER CONCEALED SPACE IN A BUILDING, GAS VENT OR CHIMNEY. THIS COULD CREATE A FIRE HAZARD FROM LINT EXPELLED BY THE DRYER.

6 The exhaust duct should end with an exhaust hood with a swing-out flap to prevent back-draughts and access for wildlife (see Accessories). Never use an exhaust hood with a magnetic flap. The hood should have at least 300mm (12 ) clearance between the bottom of the hood and the ground or other obstruction. The hood opening should point down. Never install a screen over the exhaust outlet. When possible, do not exhaust the dryer directly into a basement window well in order to avoid a lint build-up. Do not exhaust under a building. If exhaust ductwork must run through an unheated area, the duct should be insulated and slope slightly down towards the exhaust hood to reduce condensation and lint build-up. If an existing exhaust system is to be used with your new machine, you must ensure: The exhaust system meets all local and national regulations That plastic flexible duct is not used. To completely inspect and clean all lint accumulation from the duct interior. The duct is not kinked or crushed which could restrict airflow. The exhaust hood flap opens and closes freely. If multiple units are exhausted into a common duct: 1. An exhaust cross-section area of 78cm 2 ( ) is required per dryer. This will allow for free air movement should all dryers be operated simultaneously. 2. A power exhaust may be used on multiple installations. 3. Ducts larger than 100mm (4 ) diameter can result in increased lint accumulation. Such lint accumulation should be cleaned regularly. 4. Exhaust ducting should be kept as short and direct as possible. The operating pressure in the exhaust system must not exceed 23mm (0.92 ) water gauge, or be less than 0. This can be measured with the dryer(s) operating, by inserting a manometer connection at the point where the exhaust duct connects to the dryer (a no-heat part of a cycle should be used, without clothes load and with a clean lint filter). Inspect and clean the interior of the dryer exhaust system at least twice a year. Disconnect from the electricity supply prior to cleaning. Check the gas supply connection any time the machine is moved. Frequently check to be sure the exhaust hood flap opens and closes freely. 7. Electrical connection WARNING: This is a 3-wire appliance which must be earthed. The gas dryer/washer is fitted with an electrical supply cord and plug. It should be connected to an electricity supply socket at the voltage shown on the dataplate. The minimum supply fuse capacity should be 10A. The appliance must be positioned so that the plug is accessible. If the fitted plug is not used, the electrical connection must be carried out by a competent electrician in accordance with local or national wiring regulations. Do not use extension lead assemblies on commercial installations. If the supply cord is damaged, it must be replaced with a specially terminated cord by an authorized service agent or a similarly qualified person in order to avoid a hazard. The electric dryer/washer is supplied without an electric cord and plug. It must be connected to a singlephase electricity supply at the voltage shown on the dataplate, by a suitable fixed wiring installation in accordance with local and national wiring regulations. A 3-wire circular cord of minimum conductor size 2.5mm 2 cross-section area should be used. A 30A supply fuse should be used, and a switch with a minimum contact separation of 3mm in both poles must be incorporated into the fixed wiring for machine disconnection. A cord clamp bush is provided with the machine, and should be tightened on completion of wiring. The electrical mains terminals are located behind the small rear access panel at the top of the dryer, and connections should be made as shown in the figure above. Remember to replace the terminal access panel. Page 5

7 NOTE: In accordance with the European EMC Directive (89/336/EEC) the maximum electricity supply system impedance to which the electric dryer/washer should be connected is declared to be Ω + J0.155 Ω. Some local wiring regulations require connection of an additional earth bond connection to the appliance. An earthing kit (Part No ) is available. It contains the earth wire, clamp, earth screw and washer. The wire should be connected to the earth (ground) terminal on the rear panel of the dryer using the additional screw and washer shown at right. 8. Gas connection WARNING: The gas dryer is factory-set with a burner orifice for Natural Gas supply (see Technical Specification). It may be converted for use with LP (butane or propane) gas using the correct conversion kit (see Accessories). Full instructions are supplied with the kit. Before installation, check that the local distribution conditions, nature of gas and pressure, and the adjustment of the appliance are compatible. Gas installation must be carried out in accordance with any local or national gas installation regulations by a suitably qualified person. Each dryer gas inlet connection is 3/8 NPT thread. An adapter is included for conversion to ISO.7-1 thread. A 12.5mm (1/2 ) gas supply line is recommended for each dryer. For multiple unit installations the size of the main gas line must be adequate for the number of dryers (see Technical Specification for gas flow rate per dryer). Gas connection to the dryer must be made by means of a flexible gas hose suitable for the appliance and gas category (a fixed gas pipe could be damaged should the machine vibrate). A means of restraint should be used on the appliance to prevent straining of the gas supply when the appliance is moved. Remove the gas inlet connection thread protective cap. Apply jointing compound or approximately 1-1/2 turns of PTFE sealing tape over all threaded connections, and securely tighten (Note: jointing compound used must be resistant to LPG). Check for leaks as directed by local or national regulations. DO NOT use a naked flame to check for gas leaks. A pressure measurement tapping is provided on the gas valve within each dryer, accessible after removal of the front service access panel (disconnect from electricity supply before removing this panel). NOTE: All gas dryers should be disconnected from gas supply before any over-pressure testing of the gas supply system. The gas dryer uses an automatic ignition system to ignite the burner. There is no constant burning pilot light. 9. Water supply connection EARTH BOND SCREW (GROUND) Cold water supply: Pressure: MPa ( p.s.i.) Temperature: 25 C max. (77 F max.) Hot water supply: Pressure: MPa ( p.s.i.) Temperature: 49 C 60 C (120 F 140 F) These water pressures are required to correctly fill the washer in the proper time. Pressures of less than 0.2 MPa may cause a malfunction in the machine water valve, and it may also not shut off completely. Fit water supply stop-taps to allow easy disconnection of fill hoses. Always turn taps off when washer is not in use (make sure they are accessible). Page 6

8 Connect inlet hoses to water supplies using screen washer at tap connections. NOTE: Accessory inlet hoses are available tin various lengths up to 3m (10 ). Ensure the correct hose end is used on each hose. The appliance end has an NPT thread. The water supply end has a standard European 3/4 BSP thread. Do not overtighten hose connections. Hand tight should be adequate to avoid leaks without damaging the sealing washer. 10. Drain hose connection Install gooseneck end of drain hose into a standpipe. Be sure an air-tight connection is NOT made between the drain hose and the standpipe. Recommended height of the standpipe is 0.9m (36 ). If the standpipe is less than 0.6m (24 ) high, the drain hose should be routed through the clip to raise the hose to the proper height. Standpipe must be large enough to accept the outside diameter of the drain hose. If a floor drain is used, route the drain hose through the drain hose clip before routing to the drain. Without the 0.6m (24 ) high elevation, water may run out of the washer prematurely. NOTE: Caution must always be exercised to avoid kinking the drain hose. For best performance the drain hose should not be restricted in any way, through elbows, couplings or excessive lengths. HOSE RETAINER CLIP To prevent accidental dislodging secure the drain hose to the standpipe, inlet hose or laundry tub with the tie strap provided in the parts package. 11.

9 12. Final installation checklist Instructions and Installation Kit have been removed from inside. Shipping straps have been removed. Appliance has been properly levelled. All legs should be firmly on the floor and lock nuts MUST be tightened. Water is turned on and checked for leaks at tap and water valve connections. Appliance is connected to electricity supply and is properly earthed. Drain hose is properly located into drain facility and is not kinked. All exhaust and gas connections to dryer are correctly made. Turn on gas supply (where applicable). Turn on water supplies. Switch on electricity supply. Following Operating Instructions, check the operation of the dryer first, then the washer. Dryer On gas dryers the burner may not ignite initially due to air in the gas pipework. Allowing the dryer to operate on a heat setting will purge the pipework. If the gas does not ignite within 5 minutes, turn the dryer off and wait for 5 more minutes. Make sure gas supply has been turned on. In order to confirm gas ignition and correct operation of the burner (mostly blue flame) the professional installation engineer may remove the front access panel to view the burner. WARNING: Do not touch any electrical parts and replace panel immediately after this check. To confirm gas ignition at any other time, the exhaust duct should be checked for heat. Washer Ensure washer fills properly on all temperature selections. Test for proper operation by running the washer through a complete cycle. Page 8
